You gain a swim speed equal to your base land speed and a +8 racial bonus on Swim checks. If you already have a swim speed, your base swim speed increases by 30 feet. You can hold your breath for a number of minutes equal to 10 × your Constitution score, but afterward you must succeed at checks as normal to avoid drowning. If you expend one use of mythic power, for 1 hour your base swim speed increases by 10 feet per mythic tier.
